Embodiment 2

[0020] The difference between this embodiment and the first embodiment is that the water outlet pipe 22 is connected to the condensing device, and the condensing device is connected to the water inlet pipe 21 . The condensing device adopts a water-cooled screw-type low-temperature chiller (brand ONTAS, which can be customized according to the specific conditions of the process) to cool the water. The water in the outlet pipe 22 flows into the water-cooled screw-type low-temperature chiller at a higher temperature, and then The lower temperature flows out from the water-cooled screw low-temperature chiller, and enters the inner cavity 32 of the spiral tube through the water inlet pipe 21 . This scheme realizes water recycling and saves energy.

Embodiment 3

[0022] The difference between this embodiment and the first embodiment is that it also includes a water pipe joint, which is respectively installed at the water outlet pipe and the water inlet pipe, and the water pipe joint can be connected to a heating device. The water pipe joint at the water outlet pipe 22 is connected to the radiator or the floor heating pipe, and the other end of the radiator or the floor heating pipe is connected to the water pipe joint of the water inlet pipe 21 . This method realizes turning waste into treasure. The high-temperature water flowing out of the water outlet pipe 22 exchanges heat with the indoor cold air in the radiator or floor heating pipe to become low-temperature water, and then enters the inner cavity of the spiral casing through the water inlet pipe 21 32, so cycle. This scheme transfers the heat in the molding sand to the indoor air through water for daily heating. This realizes the effective utilization of energy, energy saving an...

Embodiment 4

[0024] The difference between this embodiment and Embodiment 1 is that both the water outlet pipe and the water inlet pipe are provided with Y-shaped water pipe joints, and the Y-shaped water pipe joints are respectively connected with the water outlet / inlet pipe, the condensing device, and the heating device; the connection between the condensing device and the water outlet pipe There is a valve between the Y-shaped water pipe joint, a valve is provided between the condensing device and the Y-shaped water pipe joint of the water inlet pipe; Valves are arranged between the water pipe joints. In this way, when the weather is cold and heating is needed, open the valves connected on both sides of the heating device and close the valves connected on both sides of the condensing device; valve. This method uses energy more flexibly and effectively and reduces the material temperature.

Abstract

The invention discloses a spiral cooling device used for cooling treatment of particles and powder and relates to the field of casting and powder metallurgy. The spiral cooling device comprises a feeding port, a spiral sleeve, a discharging port, a water inlet pipe and a water outlet pipe. The spiral sleeve is divided into an inner pipe and an outer pipe; an opening in the lower end of a middle cavity is connected with the water inlet pipe, and the upper end of the middle cavity is connected with the water outlet pipe; the middle cavity between the inner pipe and the outer pipe is filled with water flowing from bottom to top; the upper end of the inner pipe is connected with the feeding port, and the lower end of the inner pipe is connected with the discharging port. When materials to be cooled slide downwards along the spiral inner pipe, heat is transferred to the flowing water in the gap between the inner pipe and the outer pipe, and therefore the temperature is lowered. The spiral cooling device is simple in structure; by means of a closed type pipe structure, the local air pollution is reduced; by means of the spiral design, the time that the materials pass through the flowing water is prolonged; by means of the pipe sliding design, the effective contact area between the materials and the flowing water is enlarged; the environment protection is achieved, and the cooling efficiency is improved.

Description

technical field [0001] The invention discloses a spiral cooling device, which relates to the fields of casting and powder metallurgy, and is especially used for cooling treatment of particles and powders. Background technique [0002] Castings are widely used in various mechanical equipment, and castings are products produced through casting processes. The most widely used casting process is to use quartz sand for molding or other sands with high refractoriness. In order to save resources, the state has stipulated the utilization rate of old sand. One of the casting processes with the highest utilization rate of old sand is lost foam casting, V law casting. In both casting processes, sand is used to assist molding. Molding sand absorbs a lot of heat from the casting during the molding process, and its temperature must be lowered before it can be recycled. [0003] The molding sand cooling equipment widely used in foundry production process is boiling cooling bed. The wor...
